Here’s a neat little app for weather that can also double as a screen saver. This is free with no ads, or you can upgrade for $10 bucks to get more variety of backgrounds.
The backgrounds are animated with sound and reflect the weather that is current and forecasted. The backgrounds change lighting and atmosphere as the day turns to night.
I’m likin’ this app…It’s fun! 
Btw, I bought the premium. Figured I liked it and might as well help out someone who took the time to develope this very creative weather app.
